TURN-TABLE FOR INCUBATORS.

Specification of Letters Patent.

Patented June 9, 1908.

To all whom it may concern:

Be it known that -we, CORNELIUS Von- HEES SNEDEKER and J ESSE DE TITE WAR both citizens of the United States, and residents of Savannah, in the county of Chatham and State of Georgia, have invented a new and useful Improvement in Turn-Tables for Incubators, of which the following is a full, clear, and exact description.

The purpose of our invention is to provide a turn table for incubators, or an attachment to an incubator upon which a tray of eggs can be slid directly from the incubator upon a turn table and turned thereby end for end to be again returned directly to the incubator, thereby effecting a shifting of the eggs in a rapid and convenient manner and Without danger of agitating the contents of the shells.

A further purpose of the invention is to provide a device of the character described, which will be simple, durable and adjustable, capable of application to any standard incubator, and which, when not required for use, can be folded down out of the way.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicatecorresponding parts in all thefigures.

Figure 1 is a front elevation of the body portion of the incubator, and a front elevation of the attachment set up for use; Fig. 2 is a vertical section, taken practically on the line 2-2 of Fig. 4, the turn table being shown in full lines in receiving position and the tray as partially drawn out from the body of the incubator, the said tray and. turntable being also shown in dotted lines in po sition to be revolved; Fig. 3 is a transverse section or a section extending from side to side, taken practically on the line 33 of Fig. 4; and Fig. 4 is a plan view of the device, parts being broken away, showing the turn table in receiving position'in full lines, and as partially turned in dotted lines, the body of the incubator being in section and the section being taken on the line 44 of Fig. 1.

A represents the body of an incubator, and A its supporting legs. The body of the in cubator is provided with a door that is preferably a drop door 10, as is illustrated in Figs. 1, 2, and 4, and a suitable latch 11 is arranged to normally look the door in closed position. This door 10 is connected to the incubator by hinges 10 and is adapted to close the entrance to a chamber 13 in the body A of the incubator, in which chamber the tray or trays C are placed, carrying the eggs, the trays being adapted to slide on the conventional ways at the said portions of the chamber.

The body of the attachment consists of a supporting frame D which is of rectangular shape, and comprises parallel side members 14 that are connected with the side portions of the body of the incubator, where the door 10 is located, by means of suitable hinges 15. The sidemembers 14 of the frame D are connected at their front portions by a cross bar or member 16, and a second parallel and intermediate cross bar 17 is provided, as is shown in Fig. 4. The construction of the frame D is completed by the addition of two short intermediate beams 18 and 19 that extend from the intermediate cross bars 17 to the front bar 16, being located one at each side of the center of said. bar, and a space 20 is provided between the short longitudinal bars 18 and 19 for a purpose to be hereinafter described. It will be observed that there is ample space between the cross bar 17 and the side of the incubator to which the attachment is applied for the ready downward or upward movement of the aforesaid door 10.

The frame is held in operative or horizontal position as is shown in Figs. 1, 2, and 4, by

means of arms 21 pivoted at their upper ends in suitable recesses 22 produced in the inner faces of the side members or longitudinal bars 14 of the frame, the lower ends of the arms 21 are free to slide loosely in recesses 23 made, for example, in the inner faces of opposing legs A, as is shown in Figs. 1 and 2, and in each of the recesses 23, a horizontal pin 24 is located, and when the frame is in its horizontal position, the pins 24 are received in recesses 25 made in the lower edges of the aforesaid arms 21 at their lower terminal portions, as is also shown in Fig. 2. The arms 21 are held in position to be engaged by the pins 24 by means of springs 26 that are also carried by the legs and extend from the upper portions of the recesses 23 to a suitable bearing upon the upper edges of the arms 21, where said arms pass through said recesses. Thus in practice when it is desired to drop the frame D, it is simply necessary to disengage the recessed portions of the arms 21 from the pins 24 whereupon their lower longitudinal straight edges will slide rearwardly over the pins, ermitting the frame D to drop downward c ose to the side of the incubator box.

The frame D is adapted to carry a turn table E upon its upper face. This turn table is best shown in Figs. 2, 3, and 4, and consists of longitudinal side or track bars 27, each having a recess 28 in its upper face at its longitudinal edge extending from end to end, as best shown in Fig. 4. The recessed portions 28 of the track bars are adapted to receive the side edges of the tray C when said tray has been drawn out from the compartment 13, and it may be here remarked that in placing the attachment on an incubator, the height at which it is placed is such that when the frame D is in horizontal position, the recessed portions 28 of the track bars 27 of the turn table will be in alinement with the upper edges of the ways for the trays located in the incubator chamber 13.

In the further construction of the turn table E, a connecting bar 29 is employed that is attached to the bottom central portions of the track bars 27, and a central supporting bar 30 is likewise employed, being parallel with the track bars, and by preference this intermediate supporting bar 30 is recessed at its bottom to receive the connecting bar 29.

When a turn table is constructed as described and shown, it will receive a single tray, or two smaller trays. -When a single tray is to be received, the side edges of the tray rest upon the track surfaces 28 of the track bars 27, but when two small trays are to be supported by the turn table, the outer side edges of the trays rest upon the track surfaces 28 of the track bars 27, while their side edges rest upon the intermediate supporting bar 30.

The connection between the turn table E and the frame D is effected through the medium of a pivot bolt 31 that is secured in any approved manner to the central portion of the supporting bar 30, being carried down through the connecting bar 29, and loosely through the space 20 between the longitudinal short bars 18 and 19 of the frame, as isshown in Fig. 2, and this bolt is provided at its lower end with a thumb nut 32, or the equivalent thereof. By loosening this thumb nut the turn table may be revolved and turned end for end, and after the adjustment has been made, upon tightening the nut 32, the turn table is held rigidly in adjusted position.

It will be observed that the inner portion of the frame D presents no detrimental obstructions between its side members 14 so that the door 10 may be drop ed down and raised without hindrance, ena ling the tray or trays to be readily removed from the incubator, and while the frame is in operative position, the door 10 having been opened, the turn table is slid in direction of the body of the incubator, as far as possible, as is shown in full lines in Fig. 1, and then the tray is withdrawn from the chamber 13, and in leaving its slide-ways it passes gently upon the track surfaces 28 of the track bars of the turn table. When a tray is slid upon the turn table the turn table is drawn outward as far as possible, as is shown in dotted lines in Figs. 1 and 4, the movement of the turn table in its in and out direction being limited by the length of the space 20, and after the turn table has been thus carried outward, it is turned upon its pivot until the tray carried thereby has been turned end for end, or its position just reversed with relation to the incubator, then the tray is slid into the aforesaid chamber 13. The turn table is now again drawn outward to permit the door 10 to be closed and the entire attachment is dropped to a lower vertical position out of the way until again required for use, by shifting the position of the supporting arms 21.

Having thus described our invention, we claim as new and desire to secure by Letters Patent,

1. A tray attachment for incubators consisting of a support, means for attaching the support to an incubator, and a turn table mounted on the said support.

2. A tray attachment for incubators comprising a support, means for connecting the support to an incubator, a turn table pivoted upon the said support and mounted for lateral movement to and from the incubator.

3. In a tray attachment for incubators, a support hinged to an incubator, a turn table pivoted upon said support and mounted for longitudinal movement to and from the incubator, means for looking the turn table in adjusted position, and means for supporting the said supportin horizontal position, which latter means may be operated to permit the support and the table to drop to a perpendicular position.

4. In a tray attachment for incubators, a frame, supporting arms pivotally connected with the frame, means for attaching the frame to an incubator, and a turn table mounted upon the frame and having sliding and pivotal adjustment relatively to the frame.

5. In a tray attachment for incubators, a frame provided with an elongated opening, means for attaching the frame to the incubator at the exterior thereof, supporting arms for the frame, a turn table upon the upper face of the frame, said turn table being provided with track side bars, a pivot bolt for the turn table, extending through the elongated opening in the frame, and means for tightening and loosening the said bolt Whereby said turn table is capable of rotation and lateral adjustment.

6. The combination with an incubator having an egg chamber, slideways within said chamber, and a tray supported by the said slideways, of an attachment consisting of a slotted frame having a hinge connection with the exterior of the incubator adjacent to the egg chamber therein, supporting arms pivotally connected with the frame, said incubator being provided with guides through which the supporting arms have movement, a keeper for the said supporting arms carried likewise by the incubator, a turn table located upon the upper face of the frame, having track side bars, a center supporting bar, and a connecting bar for the side bars and center bar, the track surfaces of the side bars when the frame is in horizontal or receiving position being substantially in the same horizontal position with the tray slideways in the egg-receiving chamber, a pivot-bolt passed centrally through said turn-table and through the said slot in the frame, and a lock-nut for the said bolt, whereby the turntable has not only a rotary movement but a lateral movement to and from the incubator. In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
